4 cards from this section. Quick, good the night before a test.
What is a 3D vector and how is it represented?
Think about how vectors are defined in lower dimensions.
Calculate the resultant vector for A = i + 2j + 3k and B = 2i + j + k.
Add the components from each vector together.
What does the dot product of two vectors result in?
Recall the definition of dot product.
In 3D vector representation, what do the letters i, j, k signify?
Think about what unit vectors indicate in space.
Given A = 3i + j + 2k and B = -2i + 4j + k, find both A + B and A × B.
Utilize vector addition for A + B, and the determinant method for A × B.
Show that the vectors A = 2i + 2j + 2k and B = 4i + 4j + 4k are parallel. What is their angle?
Compare components to determine parallelism.
